2What is GÉANT ?
- Pan-European Network connecting 28 NRENs from
across Europe - Based on 10Gbps capacity, using Juniper routers
- Global Research connectivity
- US, Canada, Japan
- Platform for development and deployment of
advanced services (QoS, IPv6, MPLS) - Jointly funded by NRENs and EC
3 Multi-Gigabit pan-European Research
Network Backbone Topology December 2002
- Connecting 32
- European Countries
- and 28 NRENs
- Backbone capacity in
- the range of
- 34Mb/s-10Gb/s
4Backbone Access Speeds - August 2002
5Global Research Connectivity
- 3 x 2.5Gbps connectivity between Europe (AT, DE,
UK) and US (NYC, DC) - Interconnections with Abilene, CAnet4, ESNET,
SINET - NSF funded initiative to provide 2 x 2.5Gbps
between Chicago and Amsterdam - 155Mbps connection London-Tokyo
6Global Connectivity - August 2002
7North America - May 2003

8Other Regions
- ALICE (South America)
- EUMEDCONNECT (Mediterranean)
9The ALICE Project
- America Latina Interconectada Con Europa
- The objective of ALICE is to create a regional
Latin American research networking infrastructure
and its interconnection to GEANT. The ALICE
project is co-funded by the European Commission.
10Possible Latin American network topology
- Major connectivity between AR, BR, CL, MX (at
least 45 Mbps) - Other countries connect to major nodes (between
10 and 45 Mbps) - Connectivity to Europe at least 155 Mbps
- Topology dependent on result of the ALICE tender
- IPv6, QoS, Multicast
11ALICE Timetable
- ALICE contract to be signed early April 2003
- Procurement Recommendation October 2003
- Main backbone ring (Mexico-Chile-Argentina-Brazil)
and connectivity to GEANT end 2003 - Successive network roll-out to all other
countries - EC funding will last until 31 March 2006
- Sustainability after 2006 to be ensured by CLARA
(Cooperacion Latino Americana de Redes Avanzadas) - More information Please contact Cathrin Stover,

12EUMEDCONNECT
- NRENs in Algeria, Cyprus, Egypt, Israel, Jordan,
Lebanon, Malta, Morocco, Palestinian Authority,
Syria, Tunisia, Turkey - Project Partners DANTE (UK), GARR (Italy), GRNET
(Greece), RedIRIS (Spain), RENATER (France) - Project supported by EC EUMEDIS programme

14How do we get there?
- Topology to be agreed during tender negotiations
- Initial topology could include
- Direct MED-NREN connections to GÉANT
- Satellite links
- local hubs
- Evolution to target topology as soon as
achievable - Timescales Tender currently underway
- Service from late 2003-2006
-
15The Services
- Best Efforts IP
- Premium IP
- LBE (scavenger)
- Multicast
- MPLS-based VPNs
- IPv6
- Interdomain Performance Monitoring
16Premium IP
- Separate IST project (SEQUIN) for the definition
of Premium IP - Validated, deployed on GEANT
- Based on diffserv-EF
17Architecture
Classify (DSCP) High priority queueing on all
nodes
Do not police on egress Do not shape
18Use of Premium IP
- IST projects AQUILA, MOICANE, LONG
- Request for and configuration is not yet
automated - ongoing work
- http//www.dante.net/nep/geantqos/premiumip.html
19IPv6
- GÉANT configured since February 2003 with dual
stack operation - First NREN connections next week!
- Abilene to follow in May 2003
- All other NRENs connected by October 2003
20L2 VPN
- Provision of emulated switched point to point
connections, using Juniper MPLS/CCC - 6NET STM-1 between Germany and Greece
- ATRIUM STM-4 between Poland and France
- DATATAG STM-4 between CERN and Italy
eVLBI
21What next ?
- GÉANT funding ends November 2004
- FP6 call for successor network May-September 2003
- Work for successor ( RfP, FP6 bid) starts now
22The Technical Requirements
- Support IP(v6) based services, perhaps at higher
aggregate capacities (gt 10Gbps) - Switched point to point connections, from STM-4
to 10GE - middleware for interdomain resource allocation,
AAA ? - Support for GRIDs
23Network Architecture options
- Routed (IP only)
- Mix of switched routed
- SDH or GE or both ?
- Connectivity (depends on costs and locations)
- managed wavelength/SDH
- DIY (see CH, CZ, PL, NL)
- mix of both
24Thank You
25Largest GRID Application on GÉANT yet
- VLBI - Very Long Baseline Interferometry
- e-VLBI - Real-time VLBI done using network
interconnectivity - EVN - European VLBI Network
- 14 radio telescopes in Europe
- plus others further afield
- JIVE - Joint Institute for VLBI in Europe
- hosts Mk IV correlator (dedicated supercomputer)
- JIVE hosted by ASTRON at Dwingeloo in The
Netherlands - See http//www.evlbi.org
26What is VLBI?
Radio telescope
Correlator
Data flows (RT or non-RT)
27Picture of (part of) MkIV Correlator...
28Current arrangement uses tapes...
- Tape technology nearing EOL
- One supplier left
- 1200 per tape
- Drives no longer available
- Expensive logistics
- Effectively limits bit rates
- Hence limits resolution
- Slow turn around time
- Real-time measurement not possible
- Inflexible duty cycles
